I think he looks cool that way two. It kind of gives him that mecha/anime sort of look. Kind of reminds me of a character from Gatchaman. Or one of the shorts from "Batman Gotham Knight", which was a Japanese anime take on Batman.

This would indeed be an epic battle although I think it would be short lived because they would both ask questions I think and come to the conclusion that fighting would be unnecessary and then perhaps help each other with whatever it was they were doing at the time. Just a thought because they are both farely level headed and are willing to talk to an extent.
